„ PIN CONFIGURATIONS

PIN NAME

DESCRIPTION

Analog Ground for the amplifiers. A 1μF capacitor at this pin (with a 5μF capacitor at pin 8)

1 Input(+) provides 52dB (typ) of power supply rejection. Turn-on time of the circuit is affected by the

capacitor on this pin. This pin can be used as an alternative input.

2 Input(-) Amplifier input. The input capacitor and resistor set low frequency roll-off and input impedance.

The feedback resistor is connected between this pin and output 1.

3 Output 1 Amplifier 1’s output. The DC level is about (VCC~0.7V)/2.

4

VCC DC supply voltage is applied to this pin (VCC=2~16V).

5

GND Ground pin.

Amplifier 2’s output. This signal is equal in amplitude, but 180℃ out of phase with that output 1,

6 Output 2

the DC level is about (VCC~0.7V)/2.

This pin can be used to power down the IC to converse power, or for muting, or both. When at a

7

Mute logic “LOW” (less than 0.8V), the IC is enabled for normal operation. When at a logic “HIGH” (2V

to VCC), the IC is disabled. If Mute is open, that is equivalent to a logic “LOW”.

8

Ripple A capacitor at this pin increase power supply rejection, and affects turn-on time. This pin can be

Rejection left open if the capacitor at pin 1 is sufficient.
